State the chemical equation for the reaction that occurs when a lead-acid battery is being re-charged or discharged |
|
Answer» Lead and lead DIOXIDE, the active materials on the battery's plates, react with sulfuric acid in the electrolyte to form lead SULFATE. The lead sulfate first forms in a finely divided, amorphous state and easily REVERTS to lead, lead dioxide, and sulfuric acid when the battery recharges.Explanation:example anode reaction: Pb(s) + SO42-(aq) → CATHODE reaction: PBO2(s) + 4H+(aq) + SO42-(aq) + 2e - → overall reaction: Pb(s) + PbO2(s) + 4H+(aq) + 2SO42-(aq) → |
